Nef does not contribute to replication differences between R5 pre-AIDS and AIDS HIV-1 clones from patient ACH142 (2008)

Olivieri, Kevin C, Scoggins, Robert M, Broderick, Brooks, Powell, Maria LC, Alexander, Melissa A, Hammarskjöld, Marie-Louise, ...

Abstract AIDS-associated, CCR5-tropic (R5) HIV-1 clones, isolated from a patient that never developed CXCR4-tropic HIV-1, replicate to a greater extent and cause greater cytopathic effects than R5...

DBR1 siRNA inhibition of HIV-1 replication (2005)

Ye, Ying, De Leon, Jessica, Yokoyama, Noriko, Naidu, Yathi, Camerini, David

Abstract Background HIV-1 and all retroviruses are related to retroelements of simpler organisms such as the yeast Ty elements. Recent work has suggested that the yeast retroelement Ty1 replicates...

Background: HIV-1 and all retroviruses are related to retroelements of simpler organisms such as the yeast Ty elements. Recent work has suggested that the yeast retroelement Ty1 replicates via an...

Human Immunodeficiency Virus Type 1 Pathogenesis in SCID-hu Mice Correlates with Syncytium-Inducing Phenotype and Viral Replication

Camerini, David, Su, Hua-Poo, Gamez-Torre, Graciela, Johnson, Michael L., Zack, Jerome A., Chen, Irvin S. Y.

Human immunodeficiency virus type 1 (HIV-1) patient isolates and molecular clones were used to analyze the determinants responsible for human CD4+ thymocyte depletion in SCID-hu mice....

Pathogenesis of Primary R5 Human Immunodeficiency Virus Type 1 Clones in SCID-hu Mice

Scoggins, Robert M., Taylor, James R., Patrie, James, Van't Wout, Angélique B., Schuitemaker, Hanneke, Camerini, David

We studied the replication and cytopathicity in SCID-hu mice of R5 human immunodeficiency virus type 1 (HIV-1) biological clones from early and late stages of infection of three patients who never...

Expression and Function of Chemokine Receptors on Human Thymocytes: Implications for Infection by Human Immunodeficiency Virus Type 1

Taylor, James R., Kimbrell, Katherine C., Scoggins, Robert, Delaney, Marie, Wu, Lijun, Camerini, David

The presence or absence of the receptor CD4 and the coreceptors CCR5 and CXCR4 restrict the cell tropism of human immunodeficiency virus type 1 (HIV-1). Despite the importance of thymic infection by...

Human Immunodeficiency Virus Type 1 Vpr-Mediated G2 Arrest Requires Rad17 and Hus1 and Induces Nuclear BRCA1 and γ-H2AX Focus Formation

Zimmerman, Erik S., Chen, Junjie, Andersen, Joshua L., Ardon, Orly, DeHart, Jason L., Blackett, Jana, ...

Eukaryotic cells have evolved a complex mechanism for sensing DNA damage during genome replication. Activation of this pathway prevents entry into mitosis to allow for either DNA repair or, in the...

R5 Human Immunodeficiency Virus Type 1 Infection of Fetal Thymic Organ Culture Induces Cytokine and CCR5 Expression†

Choudhary, Shailesh K., Choudhary, Neelima R., Kimbrell, Katherine C., Colasanti, Jonathan, Ziogas, Argyrios, Kwa, David, ...

Late-stage CCR5 tropic human immunodeficiency virus type 1 (HIV-1) isolates (R5 HIV-1) can deplete nearly all CD4+ thymocytes from human thymus/liver grafts, despite the fact that fewer than 5% of...

KSHV targets multiple leukocyte lineages during long-term productive infection in NOD/SCID mice

Parsons, Christopher H., Adang, Laura A., Overdevest, Jon, O’Connor, Christine M., Taylor, J. Robert, Camerini, David, ...

To develop an animal model of Kaposi sarcoma–associated herpesvirus (KSHV) infection uniquely suited to evaluate longitudinal patterns of viral gene expression, cell tropism, and immune responses,...
